Reason 24/7 notes: A video posted at Defense Distributed's blog shows the Liberator, the organization's original design for a 3D-printed handgun, being successfully fired at a test range in Austin, Texas. Images of the components show that even the barrel and springs are plastic, with only a metal firing pin. The gun survived at least one shot, though photographs at the blog suggest that at least one receiver eventually broke.
